Domain is the set of pointsvalues that related to the independent variable (x) which make the functionequation defined! The domain of a function is the complete set of possible values of the independent variable. The domain is the set of all possible x-values, which will make the function "work", and will output real y-values. The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain. The range is the resulting y-values we get after substituting all the possible x-values. I hope that helps
